Abstract: PURPOSE:To separate and recover tin existing at a low concn. in steel scrap by increasing the amt. of slag and specifying a secondary combustion rate by using a carbonaseous material contg. S at the time of melting the steel scrap and executing floatation by recovering dust. CONSTITUTION:The steel scrap contg. the low-concn. tin is housed in a converter-like reaction vessel and oxygen is supplied to the vessel from above to burn the carbonaceous material and generated gases existing in a furnace, by which the steel scrap is melted. The amt. of the scrap in the furnace is increased to 300kg/t-metal to effifiently concentrate the Sn in the dust in this stage. The carbonaceous material contg. S at >=0.3% is used to maintain the secondary combustion rate {CO2X100/(CO+CO2)} in a 30 to 60% range.

Then, the data on the quantity of the reflected light obtained with the photoelectric transducer 5 are taken in a computer 9. Then, the arrangement of the data of the axes in two directions of the longitudinal direction and the circumferential direction is changed and the attenuation factor of the data is calculated to decide the flaw comparing with a standard value. Accordingly, since the inside of the cylindrical substance is irradiated spirally or in round slices and the quantity of the reflected light is detected, the dimensions and shape of the flaw can be detected with high precision.
